WASHINGTON (REUTERS) - United States President Donald Trump's national security adviser, Mr John Bolton, said on Tuesday (March 5) that the US would look at ramping up sanctions on North Korea if Pyongyang did not scrap its nuclear weapons programme.

Mr Bolton told Fox Business Network that following the Hanoi summit between Mr Trump and North Korean leader Kim Jong Un, Washington would see whether Pyongyang was committed to giving up its "nuclear weapons programme and everything associated with it".

"If they're not willing to do it, then I think President Trump has been very clear... they're not going to get relief from the crushing economic sanctions that have been imposed on them, and we'll look at ramping those sanctions up in fact," said Mr Bolton, a hardliner who has advocated a tough approach to North Korea in the past.

His comments came days after the Feb 27-28 denuclearistion summit between Mr Trump and Mr Kim broke down over differences on how far North Korea was willing to limit its nuclear programme and the degree of US willingness to ease sanctions.

Earlier on Tuesday, two US think tanks and South Korea's Yonhap News Agency reported that North Korea had restored part of a missile launch site it began to dismantle after pledging to do so in the first summit with Mr Trump last year.

Yonhap quoted lawmakers briefed by South Korea's National Intelligence Service (NIS) as saying that the work was taking place at the Tongchang-ri launch site and involved replacing a roof and a door at the facility.

Satellite images seen by 38 North, a Washington-based North Korea project, showed that structures on the launch pad had been rebuilt sometime between Feb 16 and last Saturday, Ms Jenny Town, managing editor at the project and an analyst at the Stimson Centre think tank, told Reuters.
